P1260 Meaning

The P1260 code may be set if the Passive Anti-Theft System (PATS) has determined that a theft condition existed and the engine is disabled or an engine start was attempted using a non-PATS key. This Diagnostic Trouble Code (DTC) is a good indicator to check PATS for DTCs. This DTC may also be set when a new Instrument Cluster (IC), Instrument Panel Cluster (IPC), or Powertrain Control Module (PCM) is installed without properly programming either module, even if the vehicle is not equipped with PATS.

Start by checking the “Possible Causes” listed above. Visually inspect the wiring harness and associated connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Technical Notes

Indicates that the Passive Anti-Theft System (PATS) has determined that a theft condition existed and the engine is disabled. This DTC is a good indicator to check PATS for DTCs.

When is the code detected?

The Engine Control Module (ECM) received a signal from the anti-theft system indicating that a violation has occurred

Possible Symptoms

  • Engine light on (or engine service warning light)
  • Starting/Stalling or Cranking/No start
